NAME
IO::File::Cycle - Easily split output file while writing
VERSION
Version 0.03
SYNOPSIS
This module makes it easy to split a file while writing to it. This, for example, will create a number of files in /tmp called "foo.1.txt", "foo.2.txt", &c., all at most 10,000 bytes in size:
use IO::File::Cycle;
my $file = IO::File::Cycle->new('>/tmp/foo.txt');
for ( 1..100_000 ) {
$file->cycle if tell($file) + length($_) + 1 > 10_000;
print $file $_, "\n";
}
$file->close;
SUBROUTINES/METHODS
start_at()
Defines the starting number, which can be easily overridden in a subclass.
open()
Sets up some internal variables, then calls IO::File::open().
format_filename()
Formats the filename.
cycle()
Closes the current file, then opens a new file with an incremented number in the filename (before the extension if there is one, and after a "."). After closing the initial file, it renames it to have the index "1" – for example, "filename.1.ext".
filename()
Returns the current file's name. This can be called from a close() method in a subclass to post-process each file.
close()
This is a sample close() method, which in a subclass could post-process each file.
sub close { my $io = shift; my $filename = $io->filename; $io->SUPER::close; system "gzip -f $filename"; }
